Ecologo-Geographic Distribution Patterns of the Italian Locust (Linnaeus) (Orthoptera: Acrididae) in the Easternmost Part of Its Range.

Grasshoppers (Acridoidea) are one of the most essential components of grassland ecosystems. They are mainly primary consumers and some of them, e.g.

The Handsome Cross Grasshopper (Germar, 1825) (Orthoptera: Acrididae) as a Neglected Pest in the South-Eastern Part of West Siberian Plain.

is a widely distributed acridid over the Eurasian semi-arid territories, from the Atlantic coast to the Pacific coast. In many semi-arid territories, was and is the most important pest, but in the south-eastern part of West Siberian Plain, it was not considered a pest until the 1960s. We compared two sets of data on the acridid distribution in the region: before 1960 and from 1961 until 2021.

The cytoskeletal protein Zyxin inhibits Shh signaling during the CNS patterning in Xenopus laevis through interaction with the transcription factor Gli1.

Zyxin is a cytoskeletal protein that controls cell movements by regulating actin filaments assembly, but it can also modulate gene expression owing to its interactions with the proteins involved in signaling cascades. Therefore, identification of proteins that interact with Zyxin in embryonic cells is a promising way to unravel mechanisms responsible for coupling of two major components of embryogenesis: morphogenetic movements and cell differentiation. Now we show that in Xenopus laevis embryos Zyxin can bind to and suppress activity of the primary effector of Sonic hedgehog (Shh) signaling cascade, the transcription factor Gli1.

[Ophthalmosurgical care in the local armed conflict].

The peculiarities of ophthalmosurgical care were studied in 62 employees and servicemen from RF Ministry for Internal Affairs (MIA) with traumatic injuries of 87 eyes (207 ophthalmosurgical interventions). It was shown that the main negative factors influencing on the treatment outcomes were the multi-staged specialized medical care, the late periods of primary surgical treatment of perforated injuries, the insufficient volume of ophthalmosurgical interventions at the stages of medical evacuation. According to the data of RF MIA Main Clinical Hospital and RF MIA Main Military Clinical Hospital the consecutive performance of ophthalmologic operations with the use of modern technologies at the stage of specialized medical care allowed decreasing significantly the number of complications, improving the outcomes of ocular severe injuries, shortening the treatment time and obtaining the highest optical result.

[Reye's syndrome--a severe complication of salicylate therapy].

Clinical and experimental data are reviewed on the Reye's syndrome--a heavy complication accompanying the therapy of viral infections in children by salicylates. Disorders in the bioenergetics of fatty acid oxidation and ammonia utilization are considered in the context of clinical manifestations of the Reye's syndrome.
